Intel Arrow Lake-S PCs may not get Microsoft’s Copilot+ certification

Published on:

Rumor mill: Intel is anticipated to launch its Arrow Lake-S desktop CPUs later this 12 months, and a slew of leaks have already revealed some key particulars about them. A tipster has now seemingly disclosed much more details about the upcoming processors, together with their NPU efficiency and cache configurations.

Arrow Lake-S CPUs will include a built-in NPU able to performing 13 trillion operations per second (TOPS) in accordance with a brand new leak. They’re additionally anticipated to supply as much as 15 CPU TOPS and 9 GPU TOPS, totaling 37 TOPS of AI efficiency.

These numbers are considerably larger than these of the Raptor Lake-S processors, which supply solely 11 TOPS of AI efficiency, together with eight CPU TOPS and three GPU TOPS. Raptor Lake CPUs wouldn’t have a built-in NPU.

Arrow Lake’s rumored 37 TOPS is similar to the 39 mixed TOPS provided by AMD’s Hawk Level APUs however falls far behind Strix Level and Lunar Lake, each of which supply upwards of 45 TOPS.

As for the NPU within the Arrow Lake-S CPUs, its 13 TOPS is healthier than AMD’s upcoming Ryzen 9000 lineup, which does not have an NPU in any respect, however falls nicely in need of the 40 TOPS benchmark mandated by Microsoft for its “Copilot+ PC” certification.

In one other submit, @Jaykihn claimed that Arrow Lake-S and Arrow Lake-HX CPUs will include a distinct cache construction than Lunar Lake regardless of utilizing the identical Lion Cove P-Cores and Skymont E-Cores. The upcoming chips will reportedly ship with 3 MB (12-Manner) L2 cache per P-Core and 4 MB (16-Manner) L2 cache per E-Core cluster, whereas L3 cache is anticipated to be 3 MB per P-Core and three MB per E-Core cluster.

For reference, Lunar Lake presents 2.5 MB (10-way) of L2 cache per P-Core and the identical 4 MB (16-way) L2 cache per E-Core cluster. Lunar Lake chips additionally function the identical 3 MB L3 cache for the P-Cores, however the LP-E cores wouldn’t have devoted L3 cache.

The tipster additionally mentioned Intel might launch an Arrow Lake Refresh lineup with an NPU improve however didn’t specify whether or not it’ll use the most recent NPU4 structure seen within the Lunar Lake CPUs. It’s believed that the unique Arrow Lake lineup is utilizing an older NPU structure, which is why it is not in a position to match Lunar Lake when it comes to NPU efficiency.
